After the production of LED and 3D displays, a new generation of televisions and screens entered the market last year. Today, most reputable brands such as LG, Sony, Samsung, etc. have unveiled their 4K TVs, and with the entry of other brands into this field, the competition in the production of 4K TVs and screens has become more heated.
4K (in English: 4K) is a standard image resolution in video recording and computer graphics cards. The number of pixels in the Forky format is four times that of the Full HD format. But the UHD standard is exactly 3840×2160. Compared to the previous QHD standard which was 2560 x 1440, 4K has exactly twice the size and depth. The resolution of this format is 4000 pixels per horizontal resolution. YouTube is a service in which this format is used.
HD TVs with 1080p quality; They have a resolution of 1920 x 1080 pixels, and in the 4K standard, this resolution reaches 4096 x 2160 pixels. That is four times the standard 1080p resolution that is currently available on HDTVs and Blu-ray discs. What is 4K technology?
UHD 4K has a resolution of 3840 pixels x 2160 pixels (Line8.3 megapixels, 16:9 aspect ratio) and is one of the two ultra high definition television resolutions.

But what is 4K Ultra HD resolution?
Like HD resolution, Ultra HD resolution includes two: 4K and 8K. 4K resolution is actually achieved by doubling the resolution of 1080p, both in length and width. As a result, this resolution is equal to 3840 x 2160 pixels, which some manufacturers display with the symbol 2160p. This resolution is exactly 4 times the number of pixels of 1080p.
But the 8K resolution is still double the 4K resolution in length and width, resulting in a resolution of 7680 x 4320 pixels. 16x resolution at 1080p. Of course, this resolution is not yet popular for home use. In the picture below, you can easily see everything that was said above, clearly and clearly.
